Description

  The present invention relates to a wearable device, and more particularly to a wearable device that employs a piezoelectric-driven micro air pump to detect physiological data.

  In today's society where personal stress continues to increase with an emphasis on speed, there is an increasing awareness of pursuing personal health, and an increasing number of people want to monitor or confirm their health status on a regular basis. . In general, data measurement for obtaining information on the physiology and health of the human body has been mainly performed with fixed blood pressure monitors and measuring devices with large volumes. These measuring devices are usually motor-type air pumps and air It includes parts such as bags, sensors, exhaust valves, batteries, etc. Among them, motor type air pumps are prone to frictional wear, and the volume after assembly of these parts is very large, so they are not suitable for geometric use. It is disadvantageous. However, if a motor-type air pump having a relatively small volume is used, the wear rate becomes faster and more energy is consumed.

  Wearable health monitoring devices are now increasing in the market to allow ordinary people to regularly monitor their health status and make it easier to carry monitoring devices. However, wearable health monitoring devices often found in the market usually measure with an optical measurement method, but this optical measurement method is low in accuracy, often leading to the generation of error values and effectively providing reliable data. I can't get it. This makes it difficult for the user to obtain accurate data about his / her health, which is likely to cause a determination error. On the other hand, when an accurate measurement method is selected, the error value becomes relatively small and more accurate data can be obtained, but the time required for accurate measurement also becomes longer.

  Usually, when it is desired to measure physiological data of a measurement subject, generally, as shown in FIG. 1, the position of the head 1a, the heart 1b, the wrist 1c or the ankle 1d is selected and measured. These positions are the easiest positions in the human body to measure data such as pulse, blood pressure, and heart rate. By measuring at these positions, the physiological and health information of the person being measured can be grasped quickly and effectively. can do. However, as described above, when an optical measurement type wearable health monitoring device is adopted, the accuracy is low, the measured data cannot be trusted, and the above-described general sphygmomanometer with higher reliability is also available. When measuring devices are used, the volume of these devices is too large to achieve the goals of lightness, thinness, and ease of portability, and it takes a long time to measure with measuring devices. It is inconvenient at the time of actual use when it is necessary to immediately know the physiological / health information measured.
